Ds2 (just 4) has this odd little ritual at bedtime. I (or dh) reads him a story, then we sing Twinkle Twinkle, then he settles himself and goes to sleep. No, that's not the odd part! He has a drinking bottle of water by his bed and he has to have a little drink before we sing Twinkle Twinkle, and a little drink after we've sung it. This routine cannot be deviated from.
Last night he forgot his little 'before' drink and so he wanted to "start all over again". I was tired and grumpy and I said no, it was silly. Cue utter screaming hab-dabs for about 10 minutes ("it's silly, ds2" "it's not silly to me!") after which I had to concede defeat because he was just about as upset as I've ever seen him - terror as opposed to tantrum.
He had his drink, I sang it again, he had another drink - all was calm, he went to sleep.
So, is this the tip of an OCD iceberg or should I just let him have his little ritual and go along with it? I say "should I let" - doesn't seem I can stop him.
Any thoughts most welcome.
Btw, he has other little idiosyncrasies - like wearing socks in bed (even in summer) but is otherwise pretty straight down the line typical 4 year old.
